  2. Arsenic contamination of groundwater - Wikipedia

    en.wikipedia.org/wiki/Arsenic_contamination_of...

    Arsenic contamination of groundwater is a form of groundwater pollution which is often due to naturally occurring high concentrations of arsenic in deeper levels of groundwater. It is a high-profile problem due to the use of deep tube wells for water supply in the Ganges Delta , causing serious arsenic poisoning to large numbers of people.

    en.wikipedia.org/wiki/Groundwater_pollution

    Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.

    Surface and ground water stagnation; Trapped water stagnation. The water may be trapped in human artifacts (discarded cans, plant pots, tires, dug-outs, roofs, etc.), as well as in natural containers, such as hollow tree trunks, leaf sheaths, etc. To avoid ground and surface water stagnation, the drainage of surface and subsoil is advised.

    In many areas of the world, groundwater pollution poses a hazard to the wellbeing of people and ecosystems. One-quarter of the world's population depends on groundwater for drinking, yet concentrated recharging is known to carry short-lived contaminants into carbonate aquifers and jeopardize the purity of those waters. [51]

    Humans can access the water that collects in an aquifer by building wells to pump the water to the surface for use. About 40% of drinking water in America comes from groundwater sources. [ 15 ] When contaminants enter aquifers, the pollution spreads, eliminating the potential to use the aquifer for drinking water.

    Unfortunately, hydrological and geological conditions in Chernobyl area promoted rapid radionuclide migration to subsurface water network. These factors include flat terrain, abundant precipitation and highly permeable sandy sediments [4] Main natural factors of nuclides migration in the region can be divided into four groups, including: weather and climate-related (evaporation and ...
